UNITED lSTATES WILLIAM RFCHYNOWETH, 0F BATTLE CREEK, MICHIGAN.

BRUSH.

Application filed August 7, 1922. Serial No. 580,198.

To all whom it may concern Be it known that I, WILLIAM R. CHYNo- WETH, acitizen of the United States, residing at Battle Creek, in the county ofCalhoun and State of Michigan, have invented new and useful Improvementsin Brushes, of which the following is a specification.

This invention relates to improvements in tooth brushes or teethcleansing and polishing devices and has for an object the provision of asimple and efficient device, by means of which teeth may be easily keptin a healthful and attractive condition.

Another object of the invention is the provision of a device of theabove character which includes a removable cleansin medium, which may ormay not be medlcated and which provides a casing or housing so as topractically enclose the device, the said cleansing medium beingrenewable at each cleansing operation.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illus- -trated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation of a ltooth brush vconstructedin accordance with the inven tion.

Figure 2 is a plan view of the same. Figure 3 is a longitudinalsectional view.

Figure 4 is a transverse section. Figure 5 is a detail perspective viewof one end of the tooth brush showing the brushing or sustainingstructure.

Figure 6 is a detail perspective view of the cleansing element.

Figure 7 is a detail perspective view of a modified form of cleansingelement.

Figure 8 is a longitudinal sectional view of the same.

Figure 9 is a perspective view of a still further modified form ofcleansing element. Referring in detail to the drawings, and moreespecially` to Figures 1 to 5 inclusive, the reference character 15indicates a. tooth brush, one end of which is formed to provide a head16, from which extends a handle 17. The head may be of the same materialas the handle, or it may be of felt, rubber, or other .compressible orsemirigid material, WherebyA proper pressure may be applied to the teethwithout discomfort. The head structure 16 is preferably provided alongits face with eorrugations 18 or the like so as to provide projectionswhich will lit the surfaces of the teeth.

Removably positioned over the head 16 is a cleansing element 19. Thiscleansing element is in the form of a casing or housing which receivesand encloses the head and is constructed of an absorbent material ofsuitable character, such for example as the material used in themanufacture of pa er towels. The element 19 may be and pre erably ismedicated or impregnated with a dentifrice and is so treated that salivafrom the mouth of the user will moisten the dentifrice so as to insureproper cleansing and curing the cleansing element upon the head,

such for example as by providing the edges of the cleansing element withan inwardly extending rib 24 which is received within a groove 25surrounding the base of i thc head 18. 4

If desired, the brush may be provided with -a cross sectionally V-shapedrib which extendsfrom the back at one end of the brush, and this rib maybe covered by the cleansing lnedium, an extension 3() which is shown inFigure 9, being provided for this purpose. This provides a relativelysharp member which will facilitate the removal of foreign matter frombetween the teeth. The invention is susceptible of various changes inits form', proportions and minor details of construction and the rightis herein reserved to make such changes as properly fall within thescope of the appended claims.

Having described the invention what is claimed is 1. A tooth brush ofthe character described comprising a handle having a head formed interally of and projecting from one of the sldes, said head being providedalong its face with transverse corrugations providing projections and acleansing eleles ment havinga pocket formed byside and end Wallsrespectively in which said head is received and provided with atransversely corrugated workingface coinciding with the corrugations onsaid head, the Walls ofthe cleansing element gripping the walls of the*lead to retain the cleansing element in place.

2. As a new article of manufacture, a handale having a head projectingfrom one end thereof and having its f ace transversely cor-
